How about :

struct Frame{
int imgfmt;//RGB, BGR,yv12,yuyv
void * base0;//R or B or Y
void * base1;//G or      V or U
void * base2;//B or R of U or V
void * base3;//Quantization Table for pp
int x,y;
int stride0;
int stride1;
int flags;//can we write in this frame? (minimize
coping of frames when pp)
...//more ideas
};

int convert(struct Frame *dst,struct Frame *src){
if( dst->imgfmt==src->imgfmt) return OK;//
if( dst->x != src->x) scalex(dst,src);
...
}
